When compiling, I get: ./../Components/ExtensionClass/ThreadLock.c:75: parse error before `type_lock' Apparently this is due to a renaming in Python between 1.5.1 and 1.5.2b1: thread.h -> pythread.h (which the code does look for) but apparently there has now been a renaming of type_lock -> PyThread_type_lock (also type_sema -> PyThread_type_sema) and free_lock -> PyThread_free_lock. I'm guessing the first change came with the 1.5.2a series and the latter came with 1.5.2b; 1.5.2b1's pythread.h definitely does not have all the renaming stuff in 1.5.1. Luckily I still had a 1.5.1 source tree lying around. Making the changes above SHOULD work for 1.5.1 as well, however, since it does do a bunch of renaming in thread.h, but if you're using 1.5.1, you probably don't need the patch.
